In about two weeks it will be one year since we lost the legendaryWhitney Houston. For the first time Houston’s mother Cissy speaks publicly about her daughter’s death in an interview with Oprah.

While the speculation continues about how she died, Cissy seems to believe drugs had nothing to do with it even though cocaine was found in the singer’s system. In an interview that will air on Monday night (1/28) Oprah asks the requisite questions. However in a segment billed as “a revelation no one saw coming” Whitney’s brother Michael is asked if he was the one who introduced the star to drugs.

Of all the people that supposedly turned Whitney on to drugs, her own brother never made anyone’s list. Check out an exclusive first look at the interview below and tune in to Oprah’s Next Chapter Monday night at 10pm.
